It's a fixie, a fixed gear bike, to brake you have to stop pedaling

@@eljigui9131 if you think about it though the gear ratio works in reverse too i think i haven't ridden a fixie before but if the gear ratio works in reverse then you get the same amount of torque back and it has very little torque so you're better off stopping by just letting air drag slow you down.

@@eljigui9131 Check back to where he puts the chains on...

@@eljigui9131 If you stop pedaling at like > 30km/h it will break your shin before slowing down a bit

@@eljigui9131 no it isn't.

probably coaster brakes

@@ethan944 I thought it also, but I didn't observe any bracket protruding from the rear hub

He made a bike built for.. *speeeeeeeeedddddd* CAUTION: brakes sold separately. Lol

That is weight reduction

Just said for speed, never implied for safety lol

This thing is just meant to have the highest gear ratio he could think of without making a front gear the size of the wheel itself. It's a proof of concept, not a product.

this is a chinese channel did you really expect them to do anything right

@@logandunlap9156 : It is often when you underestimate your opponent that you are best crushed by him.

Probably 10 to 11 gear ratio. Seen higher....

@@xXGeth270Xx 🤡

honestly just starting to pedal on this thing on flat ground seems painfully hard

that's why you get a hub motor on the front for electric assist

@@kingmasterlord Might as well get a road bike at that point, and they're faster.

I mean, get it up to 45MPH and it'll go up that hill, so long as the hill don't last too long. XD

So what direction would you go with the ratio? or, does anyone even know what the ratio he has now is lol. 😆

@@kennethferguson9828 presumably you’d do what actual bikes do, which is have a derailleur so you can start in a low gear and adjust the gear ratio as you need to.

pair it with a wheel hub gear box and you should be good to go.

It's true, ask lightning mcqueen

Its a tough call for me between the 2 you mentioned, and sloppily hole saw-ing chunks out of the frame members.

Can I have it?

Do you ever ride the bike?

Because it didn't work- nobody can go faster just because of higher gearing. In fact it would slow you down until you drop down a bunch of gears.

How did if feel?

So it is really difficult to start the bike with such a high gear ratio?

Take a while to get up to speed though.

@@BlooCollaGal Only normal to think that tbh

Can’t imagine the torque that’s lost from that ratio

I bet there's a market for this bike in The Netherlands then :D.

@@Mike-739 Just imagine the leg gains...

And poor knees...

Did you calculate the drive ratio? Must be silly

And they look a lil loose too, not so sure about this one

@@Raging-Lion yeah don't try and go up a curb, you'd lose all the chains haha

He spins the peddle backward to test it. I don't think it has breaks even with the chain.

Well, let's hope there's enough room to maneuver at the bottom of the slope

I am more shocked to see the original built quality of this bike. Ouch.

Pfft mean while Street kids and teens in my country has rusted chains and no breaks while wears flip flops and challenges each other to a drag race.

@@JomokFelasco R u from Brazil or Phillipines or Indonesia or any other ?

If you want to build a higher speed bike, i cant think how adding breaks will increase speed of the bike... 😀😀😊

@@mmeettwwoo It increases the possibility of being able to ride it again and again

I was thinking 2 sets of pedals. One set like normal bike, the other for high speed. Then you could switch between conditions (uphill-downhill etc.). Upper pedals might have smaller cranks. But then simpler to have e-bike..! :)

@@RJSoftware2000 that is actually a good ideas, a separate gear ratio for different speeds and possibly different riding positions based on the speed

@@then00brathalos or you could use a bike with a rear durrailer and even use the third and second gear on the reduction stages with front durrailers. That last idea would unfortionally make for a very complicated gear change setup with up to four shift levers.

@@then00brathalos Yeah but having that many moving stuff would reduce efficiency due to more frcition, would make the bike harder and more expensive to maintain, and would have more failure points, better to just have rear and front durrailers

you can actually use the weight of legs to pedal it is not as hard as it looks

The whole point of this project was to make a cool video, so of course some of the painting choices aren't the most practical.

Because it is single speed. But somebody has to pull/push him to start.

Yeah, but with that much torque, they can probably climb walls!

Quite a long number of years ago, Hot Rod Magazine had a article about a guy setting the bicycle paced land speed record. They built a shed on the back of a car, seems like it was a supercharged '58 Chevy. The cyclist pedaled inside the shed while the car and shed pushed the air out of the way. That bike had a front sprocket bigger than a pizza pan, as I recall.

You'll only be disappointed when you try going over 15kmh or so.

These principles in generator, really?🙄🙄 Generator requires huge torque to rotate the shaft. This setup didn't work for genarator.

@raydubBALTANseijin It does apply, but in the opposite way of what you want in a generator generally

@@sandeepvardhan7583 Generators are powered through induction, which makes little to no resistance. So if you have a high torque, you want to convert that to speed before you get a good current off it.

What effect would that have? it would still generate the same amount of power

@@ashrude1071 More friction, more parts that can wear out

I think that's 50kph, so 30mph.

50kph =/= 50mph

да нифига это не работает. По прямой на фиксе и без этой ерунды можно разогранить, не говоря о простых велосипедах. Там потери энергии просто фантастические, не говоря о том что в горку эта конструкция вообще не заедет, да и толкать эту шарагу даже по прямой долго не сможет человек без подготовки.

Самоделка полная хуйня, и я объясню почему. Вваривание в раму, в нагруженный элемент тонкостенных алюминиевых картриджей кареток - это настолько тупо, что просто разрезать раму пополам и так оставить. Люди выкидывают рамы дорогих велосипедов, когда на них появляются меленькие трещинки и боятся их варить, посколько сварной шов или пайка будет тянуть металл на себя, создавая избыточные напряжения, которые могут привести к новым трещинам. А тут он алюминиевую фольгу в раму захреначил! Так еще и нагрузку на это дал! Я вот такую тенденцию замечаю только у азиатов, чаще всего у индусов. Они берут велосипед и всеми правдами и неправдами повышают передаточное число, прибегая к таким методам, от которых сопромат впадает в ступор, и пока он из него не выйдет, конструкция работает. А, забыл спросить. У вас там вообще подъемов нет?

Есть более простые и надежные способы увеличить диапазон скоростей. 1) замена переднего чеинвилла на побольше, но не как на Мелиде автора. 2) все. Если МТБ чеинвилла не хватает, ставишь шоссейный или циклокроссовый. Если и этого не хватает, продаешь мтб и покупаешь шоссер. В кармане опустеет на несколько месяцев вперед, зато не сдохнешь от проникновения переебаной рамой в брюхо.

His gauge is in kilometers already.

You think just making the wheel spin faster will make you go faster?? You're gonna have to deal with torque as well.

@@omarrama92 ofc ? it's basic math, what are you talking about? There is no free power in this world.

@@luongtrivi You're absolutely right!! I thought you didn't know this, and thanks for the reply.

@@omarrama92 ok

That is weight reduction

The bike needs no break. The bike breaks you.

Not so "rideable" without brakes

What do you mean by efficiency? A pulley system reduces the force that needs to be applied to get momentum. You get more speed with less force applied. I don't get it what's the problem with this ?

@@MybeautifulandamazingPrincess probably efficiency in general, for example the human effort that takes to start up the bike to a reasonable speed

Frankly, gearing has never stopped me from reaching maximum speeds, it's always been aerodynamics and pulmonary / cardiovascular capacity...

@@rey_nemaattori Agreed. If anything gearing helps because it's possible to squat 400lbs compared to 20x20lbs in a second... Also agreed, it's always my cardio endurance that fails first; it'd have failed at lighter ratios just for the aerobics vs intensity. My cardio has always been terrible, hate it, hate it, hate it.

@@GRAYgauss Gearing absolutely helps, but it always is a trade off in power required per stroke. Eventually you're going to need so much power it simply becomes impossible. Especially since you're not just pressing 400 lbs in a second, but _every second_, thats when either fatigue kick in, the muscles can't move the load or the body can't supply enougj oxygen. For most people it's easier to press 20 lbs for 20 seconds that to press 400 even once .

@@rey_nemaattori Eh, bad numbers on my part. I was imagining squatting and that force that goes into pedalling when I go up hill. My point is that the human body can't move fast enough to pedal 20lbx20 in 1 second, but we COULD pedal 400lbs once in one second. For me, it's easier to pump more per cycle than many cycles, because I have terrible cardio but good mass/strength ratio. Bad numbers again, but that's the idea...The balance in my mind is most efficient when biased towards 20% speed and 80% max force rather than 80% speed at 20% force. Agreed with what you said on power, but for me I'm biased to feel that high speeds are more impossible than high torques. The fastest I can go isn't when I'm peddling like a demon, but when I'm taking about 5-6 seconds per foot to torque through and the entire follow-through feels like a rocket acceleration.

И против ветра тоже 😂

not that fast

47kph, which is about 30mph, not bad at all

@twin7s Well it's been geared up loads so I would have thought anyone could get it up to that kind of speed

@twin7s i agree, i hit a top of 30mph on my bike on flat land (i am locked out of the two hardest gears ‘cause racing regulations)

@@BillSikes. it would be a pain in the ass to get started though.

Asparagus physic obligaytion

I was honestly thinking how much force you have to put into actually getting it moving, since at such a speed he was peddaling pretty slowly

@@stefan-viorelnagy5181 he wasn't actually going as fast as the speedo showed- he altered the speedo settings to look faster.

@@rossbrumby1957 Was probably in kilometers per hour

@@jimmiew6989 Fair, I was thinking more along the lines of the first "bigwheel" bikes' user manual... it literally wrote "to stop the bike find a haystack"

Imagine if there was a motor and you can change the gear to make it slower or faster. Since it's a bike with a motor, I would probably call it a motorcycle.

Probably not a very good idea, putting that much load on a motor for that long will overheat it and reduce its lifetime and also reduce efficiency , kind of like you don't start your car at 4th gear, assuming you could even get it started at that gear. You can try out something similar at home if you just buy a simple 3V motor and power it up and then hold the shaft of the motor tight for like 2 minutes, you should notice it getting at least a bit hotter
